NVIDIA GeForce RTX 4080 with 420W TDP

As NVIDIA begins sharing first information on RTX 40 series with board partners, the rumor cycle is now shifting to SKUs below RTX 4090.

The RTX 4090 will not be the only 400W+ graphics card in the next generation of desktop series. According to reliable NVIDIA leaker, Kopite7kimi, the upcoming RTX 4080 class graphics card would ship with a power requirement of 420W.

The leaker claims that the upcoming PG139 SKU360 model, which we had already confirmed is the upcoming RTX 4080, will have a TDP of 420W. Kopite clarified that this is the full board power of the next gen RTX 4080 model. With such a TDP, the new model would have a 100W higher power requirement than the current-gen RTX 3080 model.

The RTX 4080 is expected to launch with a new GPU called AD103 (Ada), but interestingly, it would share the board with RTX 4090 (PG139). This might suggest that AD102 and AD103 are pin-compatible, and board partners will use the same cooling designs for both models.

Power increase for RTX 40 graphics cards should no longer surprise anyone. Over the weekend, the same leaker also revealed that the RTX 4060 SKU, which is expected as late as next year, would have higher TDP than the current-gen RTX 3070 model. Just assuming it’s 220W, the TDP would increase by 50W for XX60 class model.

NVIDIA GeForce RTX 4080 graphics card may launch between September and October this year. However, it is very likely that NVIDIA will be announcing this SKU alongside RTX 4090, which is expected to be released sooner.
